IMPROVEMENTIN ROLLS FOR ROLLING HCRSESHOE-BLANK BARS.

Specication forming part of Letters Patent No. 159,426, dated February2, 1875; application filed July 3l, 1874.

`To all whom it may concern:

Be it known that I, WILLIAM W. LEwIs, of

Cincinnati, in the county of Hamilton and State of Ohio, have inventedcertain Improvements in Horseshoe-Machines, of which the following is aspecification: My invention relates to machinery for roll- 1nghorseshoe-blanks 5 and consists in the construction and arrangement of apair of rolls for rolling horseshoe-blanks, one or both of which isgrooved in such manner with reference to a creaser in the groove of oneof them that the crease shall be oblique or'undercut inlthe shoe, andalso that the blank shall be full and perfect, as will be more fullydescribed hereinafter.

Figure lis a front View of arpair of rolls. Figs. 2 and 5 are sections,showing different forms of creasing devices; and Figs. 3, 4, and 6 areside views.

A B C D, Src., are grooves in one of the rolls, for forming the edgesand treads of the horseshoes. The other roll has inclined faces B' C',&c., for forming the upper side of the shoe. In the grooves A B C, Src.,are annular projections or creases a a a, for forming the crease in theshoe. The creasers, or more properly crease-liners, in grooves A and K,are mere shoulders, anddo little more than mark the line of the crease.Those in grooves B and H are somewhat deeper, and form a very slightcrease in the bar. This line or crease may then be cut to the properdepth and proportions by passing the bar through a roll with creasers ofgreater diameter.

For the better illustration of my invention, I have shown in Fig. 1grooves for forming a variety of differentshaped sh oesf that is, shoesfor diiferent kinds of work. Each of the grooves is designed to operateon and form different-shaped blanks, but they all,with the exception ofgrooves A', H', and K', embody the essentials of my invention.

Heretofore two very serious objections to machine-made horseshoes havebeen that the creasing was coarse and clumsy, and was not at the properangle to drive nails, in conformance with the natural requirements of ahorses foot, and at the same time have the nail-heads wedge tightly intothe crease.

These objections I overcome by making the faces B', 85e., which form theupper surface of the shoe, inclined to the axis of the roll, by which,as the creaser must revolve at right angles to the axis of the roll, Iobtain a crease inclined to the upper surface of the shoe-that is, anundercut crease, and the degree of under-cut may be varied by varyingthe degree of inclination of the faces B', &c. The grooves A', H', andK' represent the face of the lower By having the creaser in the groove Iam enabled to make many different forms of blanks, and especially I amenabled to make a shoe with a beveled outer edge, so that the horse willnot cut or chafe his legs by awkward motions. The inner edge, also, maybe beveled, thus making a lighter shoe, and throwing the horses weightmore on the outer crust of his hoof.

In Figs. 2, 3, and 4, at a', is shown a break in the creaser, forforming the toe portion of the shoe, and at c is another break for theheel, with a small projection, c, to mark off the bar into lengths. Thisprojection may be made larger, so as to cut the bar through,and thecreaser may be provided with projections or punches for punching thenail-holes.

Another advantage incident to the use of a roll with inclined faces B'C', &c., is, that the direct pressure of the rolls comes on the heavyparts of the blanks, which are behind the crease, and they are perfectlyformed, with clear and distinct edges. If the part in front of thecrease came under the direct action of the'roll it would result that theiron would be all pressed away from that part, and we would have,instead of a properly-formed crease, a

mere right-angled or L-shaped depression or step at the edge of the bar.

I claim as my invention- 1. A pair of improved rolls for rollinghorseshoe-blanks, of which one is grooved, and has a creaser in thegroove, and the other has an inclined face opposite the ereaser in thegroove rounded side, for producing a. horseshoe with of the first, forproducing a blank with an una beveled or rounded edge, so that the horsedercut crease, &c., as described.

2. A pair of improved rolls for rolling horseshoe-blanks, of which onehas a groove in it, with a beveled or rounded side and a creaser in thegroove, and next to the beveled or Will not cut himself when heinterferes.
